Description

Technical Field

[0001] This application relates to the field of fermenter stirring technology, and in particular to a mixing and stirring structure device for a bio-fermenter with a spiral guide plate. Background Technology

[0002] In the microbial fermentation industry, the mixing and stirring efficiency within the fermenter directly affects the growth rate of microorganisms and the yield of metabolites. The sediment in the cone-shaped area at the bottom of the tank forms a high-concentration aggregate layer due to gravity, which is difficult to effectively suspend due to insufficient fluid dynamics when conventional stirring is used, thus prolonging the fermentation cycle. Traditional mixing equipment mainly relies on mechanical stirring blades to shear and mix the substrate. However, when dealing with high-density or easily deposited microorganisms, such as mycelia, anaerobic bacteria, and algae, the stirring blades generate strong shear force when disturbing the bottom sediment, which can easily lead to damage to the microbial cell structure and loss of activity. This is especially damaging to fragile microorganisms, which seriously affects fermentation efficiency and product purity. In other words, existing technologies have the following technical problems: ordinary stirring equipment easily causes microorganisms to break down and die during stirring. Therefore, to address the above problems, a mixing and stirring structure device for a bio-fermentation tank with a spiral guide plate is proposed. Utility Model Content

[0018] Please see Figure 1-5 As shown, a mixing and stirring structure device for a bio-fermentation tank with a spiral guide plate is provided, the mixing and stirring structure device for the bio-fermentation tank with the spiral guide plate includes: Fermentation component 1, wherein a stirring component 2 is fixedly disposed on the upper surface of the fermentation component 1, and the bottom end of the stirring component 2 extends into the inner cavity of the fermentation component 1, and the stirring component 2 is used to mix and stir the microbial substrate fermenting inside the fermentation component 1. A deposition pneumatic mixing component 3 is fixedly installed on the upper surface of the fermentation component 1. The deposition pneumatic mixing component 3 is connected to the stirring component 2. The deposition pneumatic mixing component 3 is used to automatically perform pneumatic mixing on the bottom deposition area of ​​the fermentation component 1 during mixing and stirring.

[0019] Through the above technical solution, by setting the deposition pneumatic mixing component 3, the deposited microorganisms can be automatically mixed by air blowing when stirring and mixing microorganisms, thereby avoiding the phenomenon of stirring tools directly stirring the deposited microorganisms, thus greatly reducing the damage caused by stirring.

[0020] The fermentation assembly 1 includes a fermenter 101, a conical guide channel 102, and a sealing cap 104. The bottom of the fermenter 101 is provided with the conical guide channel 102, and the bottom end of the conical guide channel 102 is provided with an output end 103. The upper end of the fermenter 101 is fixedly connected with the sealing cap 104. Through this technical solution, the fermenter 101 can store the microbial substrate, allowing the microorganisms to ferment. After fermentation, the fermented product can be discharged through the output end 103.

[0021] The volume of the fermentation tank 101 is preferably 50-1000 liters to accommodate fermentation of different scales; the cone angle of the conical guide channel 102 is 45-60 degrees, and the height is 1 / 5-1 / 3 of the total height of the fermentation tank to enhance the accumulation effect of bottom sediments. A spiral guide plate 105 is fixedly connected to the inner wall of the fermenter 101, and a soft protective layer is covered on the outer surface of the spiral guide plate 105. The soft protective layer is made of food-grade silicone or polyurethane and has a thickness of 2-5 mm to provide cushioning protection and avoid mechanical damage to microorganisms. The stirring assembly 2 includes a fixed support 201, a stirring motor 202, a rotating rod 203, and stirring blades 204. The fixed support 201 is fixedly mounted on the upper surface of the fermentation assembly 1. The stirring motor 202 is fixedly connected to the upper surface of the fixed support 201. One end of the rotating rod 203 is fixedly connected to the output shaft of the stirring motor 202, and the other end of the rotating rod 203 extends into the inner cavity of the fermenter 101. Preferably, the stirring motor 202 has a power of 0.5-3 kW and an adjustable speed range of 100-500 rpm to adapt to microbial substrates of different viscosities. The bottom end of the rotating rod 203 is positioned above the conical guide groove 102. Several stirring blades 204 are fixedly connected to the arc-shaped wall of the rotating rod 203, and the surface of the stirring blades 204 is covered with a soft protective layer. Specifically, the bottom end of the rotating rod 203 is 10-50 mm away from the upper end of the conical guide channel to avoid direct contact with the sediment. Through this technical solution, the operation of the stirring motor 202 can drive the rotating rod 203 to rotate, which in turn drives the stirring blades 204 to rotate, thus stirring and mixing the internal microbial substrate. The number of stirring blades 204 is 3-6, and the length accounts for 1 / 4-1 / 2 of the diameter of the fermenter. The soft protective layer is made of the same material as the soft protective layer of the spiral guide plate, with a thickness of 1-3 mm, forming a protective layer to reduce shear stress and prevent damage to microorganisms.

[0022] The deposition pneumatic mixing assembly 3 includes a linkage unit and an air blowing unit. The linkage unit is connected to the rotating rod 203 and is used to automatically drive the air blowing unit to blow air when the rotating rod 203 rotates.

[0023] The linkage unit includes a first rotating disk 301, a second rotating disk 302, and a connecting belt 303. The first rotating disk 301 is fixedly mounted on the arc-shaped wall of the rotating rod 203. The second rotating disk 302 is mounted on the upper end face of the sealing cover 104 and is rotatably connected to the sealing cover 104. The connecting belt 303 is sleeved between the second rotating disk 302 and the first rotating disk 301. With this technical solution, when the rotating rod 203 rotates, it can drive the first rotating disk 301 to rotate, and then drive the second rotating disk 302 to rotate. Preferably, the connecting belt 303 is a synchronous toothed belt, and the first rotating disk 301 and the second rotating disk 302 are toothed synchronous pulleys to ensure reliable transmission at the stirring speed and avoid slippage. The air blowing unit includes a rotating bracket 304, a fixed cylinder 305, and a nozzle 311. The rotating bracket 304 is fixedly connected to the outer surface of the fixed cylinder 305. The bottom end of the rotating bracket 304 is rotatably connected to the upper end face of the sealing cover 104. A movable piston 306 is slidably connected in the inner cavity of the fixed cylinder 305. One end of a movable guide rod 307 is fixedly connected to the side wall of the movable piston 306. The other end of the movable guide rod 307 penetrates the inner side wall of the fixed cylinder 305 and extends to the outside of the wall. One end of the movable guide rod 307 is rotatably connected to the upper surface of the second rotating disk 302. Through this technical solution, the rotation of the second rotating disk 302 can drive one end of the movable guide rod 307 to move in a ring, thereby driving the movable guide rod 307 to move back and forth, thus driving the movable piston 306 to move back and forth in the inner cavity of the fixed cylinder 305.

[0024] Specifically, the movable piston 306 is made of polytetrafluoroethylene and is equipped with a nitrile rubber sealing ring. The gap between the piston and the inner wall of the fixed cylinder is 0.05-0.1 mm to ensure airtightness.

[0025] An input hose 308 and an output hose 309 are fixedly connected to the inner cavity of the fixed cylinder 305. One end of the input hose 308 is connected to the air source, and one end of the output hose 309 is connected to the annular pipe 310. Several nozzles 311 are fixedly connected to the annular pipe 310. One end of each nozzle 311 extends into the inner cavity of the conical guide groove 102. Check valves, preferably ball-type one-way valves, are installed on the input hose 308, the output hose 309, and the nozzles 311 to ensure unidirectional airflow. This technical solution utilizes a moving piston 306 that reciprocates within the cavity of a fixed cylinder 305. This reciprocating motion automatically draws in gas through an input hose 308, allowing the gas to enter the cavity of the fixed cylinder 305. The gas is then output through an output hose 309, entering the interior of an annular pipe 310 and finally being injected into the conical guide groove 102 through a nozzle 311. Since microorganisms tend to accumulate in the conical guide groove 102, air blowing can facilitate their movement, thus aiding in mixing. This avoids damage and tearing caused by direct contact between the stirred workpiece and the deposited microorganisms during mixing, significantly reducing the risk of microbial breakage and death.

[0026] Example 1 of connecting the inlet hose 308 to the air source: When the fermenting microorganisms need oxygen, the gas source is external oxygen. The inlet hose 308 is connected to the external oxygen source, which can automatically inject oxygen during air mixing to ensure microbial fermentation.

[0027] Example 2: Connecting the air source to the input hose 308: When the fermenting microorganisms do not require oxygen, the input hose 308 is directly connected to the upper side of the inner cavity of the fermenter 101, so that the gas in the inner cavity of the fermenter 101 serves as the gas source. The gas in the inner cavity of the fermenter 101 is circulated for auxiliary mixing, without introducing external gas, thus ensuring the fermentation of microorganisms.

[0028] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
